routing problems

[eluser]Unknown[/eluser]
if my base url is: http://localhost/tf2/ and I have a controlpanel controller...... why does http://localhost/tf2/controlpanel give me a 404 error?

$route['default_controller'] = "site";
$route['scaffolding_trigger'] = "";

those are the only routes I have.

I've tried $route['([a-z]+)'] = "index.php/($1)" but that didn't help.

Which 404 error? A CodeIgniter one or a server one?

Do you use a .htaccess file? Have a look at user_guide/general/urls.html
